04 golfstream cresendo cockpit ac and switch issues

[jpa]

hey guys i am new and am freaking out on my purchase of a 04 cresendo my ac won't even turn on i hope its a bad relay that i can't even find nothing is labeled i took the dash apart and have no power going to the ac controls and all fuses are fine so i assume maybe a relay also i have some switches that are on the right side of driver and 3 are dead i cant get power to them or seem to know where they get power from i know one goes to the small fans on the corners and also before i forget wipers and power mirrors don't work anyone has had this issues or can help me figure out what is wrong would be awesome thanks in advance.
